Who knew Irem had such a sweet tooth? The team is working on a sequel to its first PSP game, R-Type Tactics, awkwardly titled Operation Bitter Chocolate. Unlike previous R-Type games, the Tactics series strays far from its shmup origins, offering Advance Wars-esque turn-based strategy in its stead.

The debut trailer for Operation Bitter Chocolate is stylish, but we're still not entirely sure what inspired its candied name. Perhaps it's solely to bundle chocolate replicas of the franchise's iconic Arrowhead with each copy of the game. Yum.
